Optimization: Troubleshooting Slow Builds

If the builds are slow, you can set or change hive parameters at a pipeline level as follows:

• Click the Settings icon.

• Click Add Configuration.

• In the Key field, enter df_batch_hive_settings.

• In the Value field, enter the parameters you want to override. If there are multiple parameters, separate them with a semicolon (;)

For example, mapreduce.map.memory.mb=4128;mapreduce.reduce.memory.mb=5128

• Click Save.

NOTE : This setting overwrites the admin and domain configurations.

To override Hive configurations for the interactive mode, enter df_interactive_hive_settings in the Key field and enter the parameters you want to override in the value field.
